GUIDE FOR ROLLING-MILLS.

SPECIFICATION forming part of Letters Patent No. 280,093, dated June 26,1883.

Application filed May 22, 1882. (No model.)

To all whom it may concern:

Be it known that I, ALVAN A. SIMONDs, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented a new and useful Process of Manufacturing Paper-Mill Fly-Bars,of which the following is a specification.

My inventionrelates to manufacturing flybars, or rag engine cutters, ofplates of iron and steel, which, when properly heated, aresimultaneously welded and formed between suitable rolls, thereby doingexpeditiously and accuratelyin one operation that which was formerlydone tediously and less accurately by the trip-hammer.

The mechanism involved in the process is illustrated in the accompanyingdrawings, in which- Figure I is a side elevation of the rollingmachine.Fig. II is a horizontal section of the frame of the same on the line as,with a top view of the guides beneath the linear, Fig. III is a sideview of the movable guide or shim. Fig. IV is a transverse section ofthe fly bar.

Like letters of reference on the several ures designate like parts.

The general features are like the rolling-machines in use.

A represents the frame, which consists of a base and the two verticalparts B, these parts" being held together by substantial rods 0.-

Within mortises of the frame are suitable bear ings for the rollers. Onboth sides of the lower roll, and nearly on a line with its top, are twocross-pieces, G, firmly attached to the uprights. These have a series ofholes for bolts, by the means of which are secured the guides H and L.

D is a cylindrical roller, and has screws F to engage its bearings, forthe purpose of regu- J is a movable guide or shim, which is placedwithin the guide frame as a convenient means of lessening theguide-space to the varying widths of fly-bars. One or several shims maybe used for this purpose. The outer end of the shim is bent down, andthis holds it in position. The rear guide-plate, L, is bolted on to therear cross-bar, and has the rib n, which supports the adjustable guideS, against which the bar bears 011 leaving the rollers. This guide isheld in position by'the bolts 1) and 0 0, which pass through a threadedorifice in the rib and are secured by lock-nuts. Both guideframes arebolted to the cross-bars to suit the several grooves of the netherroller.

The operation is thus described: On a plate of iron of suitable lengthand width is placed a narrower plate of steel of the same length, thesteel being laid to the left edge of the iron plate. Thus prepared theplates are put into a furnace and brought to a welding-heat, then arepassed through the rolls several times, the rolls being closed a littleafter each passage, until the beveled fly-bar is in perfect form, asillustrated in cross-section at Fig. 4. After passing the rolls it isonly necessary to straighten the bar. By this process an amount of workis accomplished which could not be done b the trip-hammer operation.

The fly-bars vary in width, but in crosssection they are similar, theshorter bevel being on the edge on which the steel is laid.

Having fully described my invention, what I claim, and desire to secureby Letters Patent, 1s-

The cylindrical roller D, and the roller with obtuse periphericalgrooves, suitably supported in a frame, in combination with the frontguide, H, with its shim, and the rear guideplate, L, with adjustableguide S, held by adjustingsorews 0 0 and bolt 1;, substantially as setforth. x
